Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a gutter body used as a road cross gutter or side gutter.

``Prior art'' and ``Problems to be solved by the invention'' Conventionally, road cross ditches and side ditches have a fitting part for a lid recessed in the upper end of a concrete groove with a U-shaped cross section.
It has a structure in which a rectangular plate-shaped concrete cover is fitted into the fitting part.

According to the above-mentioned groove body structure, both the concrete groove and the concrete cover have standardized shapes and dimensions, and because they are molded by concrete pouring,
It is difficult to finish the shape and dimensions with extreme precision, and the concrete cover combined with the gutter often "wobbles." Therefore, when a vehicle passes over it or a pedestrian walks over it, it may generate abnormal noise, causing road noise pollution.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to overcome the drawbacks of the prior art described above.

``Means for Solving the Problems'' The present invention, which achieves the above objectives, ``provides a pair of opposing fitting portions with an L-shaped cutout in the upper end of the side wall of a concrete groove having a U-shaped cross section, and In a groove body assembled by placing a corner part of a concrete lid on a flat receiving part of a fitting part, a buffer member having a suction cup part on the back surface is attached to the flat receiving part,
The suction cup part is attracted to the flat receiving part, and the buffer member is interposed between the fitting part and the concrete lid.

"Example" and "Operation" A detailed explanation will be given below based on an example. In FIGS. 1 to 3 showing one embodiment, the groove body of the present invention consists of a concrete groove 1 having a U-shaped cross section and a concrete cover 2 placed on the top of the concrete groove 1, and the concrete cover 2 has a buffer member 3. It is fitted into the fitting part 4 at the upper end of the concrete groove 1 with a .

Specifically, on the inside of the upper end of the side wall of the concrete groove 1, a pair of fitting parts 4 facing each other are formed by cutting out the wall part in an L-shape, and the horizontal part of the fitting part 4 is connected to the flat receiving part 5. The corner portion of the concrete lid 2 is placed on the concrete lid 2 and the concrete lid 2 is fitted.

Further, the concrete cover 2 is formed into a rectangular plate that is fitted into the fitting part 4 of the concrete groove 1 to close the upper part of the concrete groove 1.

A shock absorbing member 3 made of synthetic rubber is placed on the flat receiving portion 5 of the fitting portion 4 of the concrete groove 1 and is fixed by suction. It is configured to be fitted into the fitting part 4. Specifically, the buffer member 3 forms a band so as to be interposed between the flat receiving part 5 and the concrete cover 2, and a group of 6 suction cup parts recessed with a large radius of curvature is formed on the lower surface in the longitudinal direction of the band. When the buffer member 3 is placed on the flat receiving part 5 and pressed, the air in the suction cup part 6 becomes diluted and is attracted to the flat receiving part 5.

In particular, in order to further improve the elasticity of the buffer member 3 of this embodiment in use, a corrugated portion 7 is attached to the portion that contacts the lower surface of the concrete lid 2, and
The end portion is bent to form an L-shape, and a piece of the buffer member 3 is interposed between the concrete cover 2 and the vertical wall portion 8 of the fitting portion 4.

According to the groove body of the present invention having the above structure, the buffer member 3 is interposed between the concrete cover 2 and the fitting part 4 of the concrete groove 1, and the buffer member 3 is supported by the suction cup part 6 on the lower surface of the buffer member 3. Since it is suction-locked to the flat receiving part 5, even if there is an unavoidable shape or dimensional discrepancy between the concrete groove 1 and the concrete lid 2 due to molding, the vibration caused by this will be avoided by the cushioning member. Absorbed by 3. Each time a vehicle or the like passes over the concrete cover 2 and a load is applied to the concrete cover 2, the suction cup portion 6 of the buffer member 3 is repeatedly compressed, so the buffer member 3 has an excellent buffering effect and , the suction locking force to the flat receiving part 5 is improved (the suction cup part 6 is compressed and the suction force is increased each time a vehicle or the like passes), and the buffer member 3 is prevented from shifting or coming off from the flat receiving part 5. There is no need to worry, and the buffering effect can be stabilized.

In addition, the buffer member 3 is placed on the fitting part 4 of the concrete groove 1 in advance, and the concrete cover 2 is placed on top of it.
Since the suction cup part 6 is compressed by the weight of the concrete cover 2 by simply placing the concrete cover 2 on it, the installation work of the buffer member 3 is extremely simple, and there are practical advantages such as easy replacement due to deterioration. .

The buffer member 3 of the present invention may be a plate-like member without vertical pieces, but if the buffer member 3 is L-shaped in cross section as in the above embodiment, it can also be interposed on the side surface of the concrete cover 2. When a vehicle passes over the concrete cover 2, it can effectively prevent the concrete cover 2 from shifting in the longitudinal direction due to the rotational resistance of the tires.
Since it is buffered, the stability of the concrete lid 2 is improved and it can further contribute to preventing abnormal noise.

``Effect of the invention'' As described above, the present invention buffers and prevents the rattling of the concrete cover of the U-shaped gutter, thereby preventing abnormal sounds and noises caused by vehicles passing by, and This has the effect of simplifying buffer construction and maintenance.
